I recently started to vape within the last 3/4 monthes. I started with a ipv4 with an arctic V8 tank that used atomizers. I recently just bought the Limitless interchangeable box mod. And the limitless color changing Rdta. This is my first time ever using a dropper and none of friends do either. What type of prebuilt coils are best there are so many different brands and styles. I currently am vaping around 100w.
